Please click on this link to learn "How to cancel a subscription from Apple" --> https://support.apple.com/HT202039
Note:
• "If you don’t see Cancel Subscription, then the subscription is already canceled and won't renew." An "Expires" date (instead of "Renews") means the current subscription will just run until then. "Resubscribe" is just in case you change your mind about it ending on the expiration date.
